Hello there! Nice work here! So cool style! :D The only issue I see is that the lighting feels inconsistent because there are two separate light sources, one on each side of the image. This makes the illustration feel less believable. Ideally, you should establish a single primary light source and use it to light both characters consistently. If you'd like, you can add a third light source in the form of a rim light to help separate the silhouettes from the background and make them stand out more. For this paintover, however, I decided to keep only the main light source. Notice how, after making this adjustment, the illustration feels much more believable because both characters are being affected by the same lighting conditions. Hope this helps!
